ABSTRACT:
An olefin resin-metal bonded structure having a desirable combination of high corrosion resistance and peel strength, which comprises a metal substrate and an olefin resin layer bonded together through a primer layer, said primer layer containing (A) an oxidized polyethylene having an oxygen content of 0.1 to 10% by weight, a saponification value of 2 to 200, a density of 0.90 to 1.2 and an average molecular weight of 1000 to 50000 and (B) a coating-forming base resin having a density higher by at least 0.1 than the oxidized polyethylene and containing a functional group selected from hydroxyl and carbonyl groups at a concentration of at least 1 meq/g, the mixing weight ratio of the oxidized polyethylene (A) and the base resin (B) being within the following range:
